True. Matter is continually cycled within the biosphere through various biological and geological processes. Organic matter is constantly being produced by photosynthesis in plants, and when organisms die or produce waste, their matter is returned to the biosphere. This continual addition of matter helps sustain the functioning and stability of the biosphere.
False. Matter is not continually added to the biosphere. The biosphere refers to the regions on Earth where organisms live, including the atmosphere, land, and oceans. The matter within the biosphere is essentially recycled and does not undergo constant addition. Elements such as carbon, nitrogen, and oxygen are continuously cycled through the biosphere's various components, including living organisms, the atmosphere, and geological processes. This process is known as biogeochemical cycling. Matter is taken up by living organisms, then released back into the environment through processes like respiration, decomposition, and excretion. This recycling of matter allows for a sustainable balance within the biosphere.
